StarCraft II: Legacy of the Void continues the story of Blizzard’s award-winning StarCraft II: Wings of Liberty where the first expansion, Heart of the Swarm®, left off, with a new campaign that brings the sci-fi saga to an epic conclusion. Protoss legends Artanis and Zeratul attempt to unite their race in an intergalactic fight for survival against an ancient evil from the Void that threatens the universe. The fates of Terran hero Jim Raynor and Kerrigan, the Queen of Blades, also hang in the balance.

StarCraft II: Legacy of Void will feature many new gameplay modes including Archon Mode, Allied Commanders mode, new multiplayer units, automated online tournaments, and more. New editor features including new terrain and upcoming features will be announced in the future.

I just want to know what Hercanic thinks of that familiar-sounding Terran barracks unit

And Cyclone to me sounds more like a Protoss ship than a Terran vehicle, given the Tempest. My own concept for the "Cyclone" was a raider craft that would slowly charge up a powerful splash shot while not attacking, but otherwise have a weak rapid-fire shot. Probably real hard to balance something like that though, even with an attack range of 4 or something.
